ROTARY DRIVING DEVICE.

To all'whom t may concern.' Y

Be it known that we, EARL W. WITTER and ARTHUR E. WITTER, citizens of the United States, and residing at Gypsum, Ohio, have invented certain new and useful Improvements in Rotary Driving Devices, of whichthe following is a specification.

Our invention relates to driving devices particularly adapted for use inV rotary curry-combs and brushes and has for its object the provision of mechanism'of the character mentioned which is simple in construction and efficient in use. l

Other objects of the invention will appear more fullyhereinaftenthe novel features of the invention being set forth distinctly inthe claims.

Referring to the accompanying l drawings, Figure 1 is an elevational view with a portion of thefcasing broken'away to show theinterior mechanism; Fig. 2 is a plan view withv portions broken away to show the rotary curry-comb and brush, gearing and the covers for the gearing; Figr is a detail View of the gear and clutch mechanism at the outer ends of the lcurry-comb and brush drum; and Fig. 4 is a cross-sectional view on the line 4-4 of Fig. 3 looking in the direction of the arrows, and shows a type of ball clutch that may be used for the purposehereinafter explained. 'I v In Fig. '1 the numeral ldesignates Ythe casing or thelframe of the device, 42 designates a cover or block attachedjto 'the jup? per surface of the casing 1, and 3 ydesignates a strap extending aicrossthe top of the device.' It lis intended that the operators hand-bie inserted through the strap '3 so as to secure a good holdon the device. If desired this strap may extend lengthwise on the block 2. 'In the lower left hand portion of the frame orl casing 1 is journaled a traction roller 4 which is covered with some frictional'material 5 such as rubberA or the like. To the outer ends of the shaftof the roller 4- are'rigi'dly connected the bevel! gears l 7, 7 The bevel-gear `7V meshes with the vrbevel-gear 8 which is'rnou'nted Von one end of the shaft '9 near'the other'end'of which is a. bevel-gear 10.

on -a shaft 9. At thev end of the shaft 9 opposite the'end carrying the gear 8 is another bevel gear 10.v The shaft 9" is journaled in the bearings 11 and12 which are carried by the brackets 18 and 14 respectively. These brackets are fastened tothe other side of the casing 1 as indicated in Fig.. 2. The bevel-gear 10 meshes with a bevel-gear 15 and the bevel-gear 10 meshes with the bevel-gear 15. The bevel-gears 15 and 15 are mounted longitudinally on the ends of the shaft 16, and are heldin place Vby means of the nuts 25 and 25 fitting on screw threaded nuts 26 and against shoulders as shown on the dotted lines of Fig. 3. These bevel-gears 15, 15 are each provided withghubs, 17 and 17 which are journaled in the bearings 18,18 in casing 1 as shown in Figs.I 2 and 3. Extending lengthwise ofthe shaft 16 is a key 19 by means of whchrthe ends or heads 20, 20 ofthe drum 21fare connected to rotate with the shaft 16. This key 19 also extends through the sleeve or collary 22 of the clutches located v`at the ends `of the drum near' the bevel-gears 15 and 15." The clutches near the-ends yof the shaft 16 are reversely arranged and each of them may be 'constructed as indicated in Figs. 3 and 4. In the lateral recesses 24, 24 are located small loose cylinders or balls 23, 23 which are free to vmove when released. When the gear`15 is actuated in "one direction the hub 17 ywill rotate freely but when moved in the opposite direction? the clutch will become operati-ve to transmit power `to the shaft/16 and-thereby rotate. the same.

The cylindrical portion 21 of the drum or the 'drum'V proper carries longitudinally curry combsA 27 an'dbrushes 28 which lare alternately arranged as shown in Fig. 1. "We prefer to havel the curry-combs .27 and brushes 28 extend in separate lines over the entire length of the drum, that is, longitudinally on theshaft of the drum. The brushes and curry-combs may however, `be arranged spirally but regularly and alter'- nately. The brushes and curry-combs may also be arranged'sectiona'lly and in 'aline ment' with each othere'ither longitudinal of the drum or s'pirally thereon; y

ATo the inner wall of one end of the casing 1 is rigidly connected a bracket 29, which: extends nearly over the entire width 0f the casing Vas indicated in Fig. 2. This site side of the rotary drum 21.

bracket carries at its inner end a brush or scraping device and engages the currycombs 27 and the brushes 28 as shown in Fig. 1, so as to dislodge the material which is carried up with such curry-combs 27 and brushes 28. Tn order to more fully effect the cleaning of the curry-combs 27 and brushes 2S another scraping brush or cleaning device 33 may be located at kthe oppo- The second cleaning device comprises bracket 31 which is secured rigidly to the partition 32 inside of the casing or frame 1. The bracket 31 and the scraping device or brush 33 carried at the inner end thereof extends longitudinally of the drinn 21 and preferably extends a short distance beyond the same at each end as shown in Fig. The brush 33 is located similarly to the brush 30 with respect to the curry-combs 27 and brushes 28, that is, in the path of the movement of the latter. The curry-combs 27 are preferably of metal and the brushes 2S of bristle. but the cleaning brushes 30 and 33 are preferably of wire, but may be of bristle if de-y sired. I

The material that is scraped by means of the brushes 30`and 33 from the curry-combs 27 and brushes 28 is collected automatically in the pans 34, 34 which are respectively hinged at 35, 35 to the casing or main frame of the device. The lateral ends of` these pans engage the said walls of the casing which determines the position of the pans when closed position as shown in Fig. 1. However, if desired, the right angle extensions 36 and 36 may be relied on to `limit the upward movement of the pans 34, 34. The pans 34, 34 connected at 37, 37 to the springs 38 and 38 the other ends of which are connected respectively at 39, 39 to the partition 32 and one of the end walls of the casting 1. These springs hold the pans in closed position or when open move them back to closed position. The pans are also provided with flanges or retaining members 40 and 40 which extend longitudinally of the drum and prevent the materials collected in the pans from owing out when the entire device is tilted to various inclinations.

To the end of the casing 1 which is opposite the end to which the roller 4 is journaled are connected the brackets 41, 41 each of which carries a sliding block 42 mounted in the guide ways 43 for vertical up and down movement. A spring 44 in each of the brackets 41 and 41 tends to hold the sliding' blocks 42 in their lowermost positions. The sliding blocks 42 of the bearings for the shaft 45 which carries an idler cylinder 46 as shown in F ig. 2. This idler cylinder extends approximately over the entire width of the rear portion of the casing 1. It is evident that when the strap 3 is grasped and the roller 4 is moved over the surface of the cleaned varying pressure On the block 2 will regulate the amount of pressure of the curry-combs 27 and brushes 28. The greater the pressure on the block 2 by means of the operators hand, particularly at the rear portion of the casing 1, the more the springs 44 will be compressed. This permits the rear end of the casing to descend closer to the surface being cleaned and therefore the drum 41 also brushes nearer the said surface. This will effect the greater pressure on the curry-combs and the brushes on the surface being cleaned, whenever necessary. But whenever desired only a slight or medium amount of pressure may be brought to bear when the rollers 4 and 46 are simply rolled over said surface.

In order to protect the gearing and prevent dust and hair from collecting in same the covers 47 and 47 are provided. These covers maybe made of separate pieces of metal attached to the lateral faces of the casing 1, Ibut if desired may be made partly or wholly integral therewith.

The shaft 9 is mounted on an inclination with respect to the surface of the casing to which it is connected. The shaft 9 is similarly arranged. This is for the purpose of providing a larger gear 10 or 10 at the end of the shaft 9 or 9 than the gear 8 or 8 at the other end of such shaft. This inclination of the shafts 9 and 9 effects the increase of the ratio of they gearing so that the drum 21 will rotate several times more than the roller 4 for any given interval. For instance if' the roller 4 rotates once and the gearing' is such that the shaft 9 will rotate once during such period, the drum 21 may be rotated about 4 times for the same period. `When the inclination of the shafts is undesirable the said shaft may be mounted on brackets of the same size so as to occupy symmetrical positions, that is, ie longitudinally ofthe casing and at equal distance therefrom. It is evident that in such arrangement the gear 8 and 10 can be of the same size but the gear 15 of smaller size or even of the same size.V The gear 7 however, must be made of larger size, than l the other gears so as to obtain an increased speed of rotation of the drum 21. If the gear 7 is of such size that for one rotation thereof the gear 8 will rotate four times the drum 21 would also rotate 4 times even if the gears 10 and 15 a-reof the same size as the gear 8. XVe, therefore, do not wish to be limited to the inclined shafts. These are shown'in the drawings to more forcibly illustrate the speed of rotation of the drum 21 with respect to the roller 4.

The operation of the apparatus hereinbefore described will now be explained. lWhen the cross strap 3 is grasped by the operator and the roller 4 is moved over a The gears will all be actuated,.but only. one

set will be effective in transmitting motion to the drum 21 because thev clutches near the ends of the shaft 16 are reversely arranged and only one of them can be effective to rotate the drum 21. The drum 21 is to be rotated always in the same direction.

This can be done by one set of gears at one side of the device by substituting a direct connectionV for the clutch connection. Then the roller 4 is moved in` a clockwise direction away from the head of the horse the gears 7, gear 15 is given an anti-clockwise direction of movement. vThe clutch within the hub 17 should therefore engage the shaft 16 to rotate the same in the direction of the arrow a as indicated in Fig. 1. The clutch at the other end of the shaft 16 in the hub 17 should at this time be free and it will be noticed that the gear 10 is arranged on the other side of the gear 15 with respect to the arrangement of the gears 10 and 15. Therefore, the shafts 9 and 9 are of different lengths. Then the roller 4 is moved in a clockwisefdirection the gear 15 is also in a clockwise direction, but if the clutch within the hub 17 operated at this timethe drum 21 would be rotated in the wrong direction. When the roller 4 is moved over the horses back in the opposite directionV however, so as to give this roller 4 an anticlockwise direction of movement the gear 15 would be given an anti-clockwise direction ofmovement. The clutch within the hub 17 at this time goes on, while the clutch within the hub 17 is free; therefore the drum 21 will be always rotated in the anti-clockwise direction of move-ment as indicated by the arrow a whether the roller 4 is rotated in one direction or the other. As before explained, when greater or Vless pressure is brought to bear on the block 2 by the operators hand the springs 44 will be compressed and the curry-combs and brushes will operate with varying effect. The cleaning brushes SO and 33 by engaging the currycombs 27 and brushes 28 will scrape off the dust and hair therefrom, which will be collected by the pans 34, 34. At any time the material. collected by the pans vmay `be ejected, and as soon as the pans are released the springs 3S and 3S will return them to their initial or closed positions.
